What KARABINER does
KARABINER (カラビナテクノロジー株式会社, Karabiner Technology Inc., DBA karabiner.inc) is a Fukuoka-headquartered Japanese IT services firm founded in 2015 and operating as a wholly-owned subsidiary of Oisix-La-Daichi Co., Ltd. since 2018. The firm delivers end-to-end digital product work — UX/UI design, web and native mobile application development (iOS/Android), EC site build and operations, AWS cloud infrastructure construction and maintenance, DX consulting, and accessibility compliance — for Japanese enterprise clients. Named customer engagements span food e-commerce (Oisix, Daichi), apparel (United Arrows), furniture e-commerce (Modan Deco's Armonia), cinema (KBC UNIE), taxi (Daiichi Kotsu Sangyo), seafood distribution (Toyoichi Gyosho), hospitality (Local Design), packaging (Yofinepack), and automotive retail (Fukuoka Kururi Motor).
The underlying technology stack covers HTML5/CSS3/JavaScript, PHP, Java, Ruby, Go, Swift, Objective-C, Kotlin, Java, plus Kotlin Multiplatform (KMP), Jetpack Compose, MVVM, Shopify customization, AWS (the firm is an AWS Select Tier Service Partner), CI/CD automation (GitHub Actions, Firebase deployment), and accessibility work aligned to WCAG 2.0/2.1 and JIS X 8341-3. A dedicated accessibility team branded tra11y (launched October 2025) responds to Japan's April 2024 amended Disability Discrimination Act. Additional productized offerings include the EC-CUBE 'Cart Gift Wrapping' plugin distributed via the EC-CUBE marketplace and an in-house coffee brand (Timeless Coffee).
The business model is primarily project-based professional services — commissioned development, DX/UX consulting, and managed maintenance contracts — sold via enterprise field sales and inside-sales channels anchored by the Fukuoka HQ. The firm operates from five Japanese locations (Fukuoka HQ, Kitakyushu, Sendai, Miyazaki, Nagano) with 100+ employees, and holds 2025 Wantedly Awards LOCAL recognition. Revenue is not publicly disclosed; the firm is privately held with no public funding rounds, IPO filings, or capital structure data in the source material.
